SIPHON.

SPECIFICATION forming part of Letters Patent No. 248,215, dated October 11, 1881 Application filedJune 25,1881. (Model) Y To all whom it may concern Be it known that I, JAMES J. Powaus, of Brooklyn, in the county of Kings and State of New York, have invented a certain new and useful Improvement in Siphons, of which the following is a specification.

The invention consists in providing a tanksiphon with an automatic valve at its outer end, and in combining with a tank and siphon having a valve at its outer end a lever pivoted to said outer end and having an adjustable weight, as hereinafter described.

In the accompanying drawing a cross-sectional elevation ofa siphon provided with my improved valve is shown.

Similar letters of reference indicate corr-- sponding parts.

A ball, A, of wood, metal, or rubber, tits in the lower end of the outer arm, B, of a siphon,

O, the inner arm, D, of which passes into a tank, E, the end of the outer arm being slightly lower than the end of the inner arm, as is customary in siphons. This ball A is mounted on a rod, F, pivoted to an arm, G, of the end of the arm B, and an adjustable balancingweight, H, is mounted on the' pivoted rod F on its end opposite the one on which the ball A is mounted.

The ball A may be replaced by a valve of any other suitable simple construction.

The rod F is shown as provided with apertures for receiving a pin 'or holding, the weight in the various positions on the bar F, butany other suitable devices maybe used in place thereof.

The operation is as follows: The contents of the tank E are to be discharged when its level reaches the line as so. As soon as the level of the water in the tank E does reach this line the weight of the water in the arm B of the siphon will be greater than the balance-weight ot' the. ball or valve A, and consequently this valve will be lowered or opened by the weight of this water, as shown in dotted lines. The water in the arm B of the siphon is suddenly discharged, and this gush is sufficient to start the siphon, causing the water to flow through the same from the tank E. As long as the water flows from the outer end of the siphon the valve A isheld open by the pressure of this water; but as soon as this flow of water ceases theweight H raises the valve A and closes the end of the outer arm, B, of the siphon and keeps it closed until a sutticient quantity of water has collected in this arm B to charge or start the siphon. The balancing-weight H must be so adjusted on the rod F that the valve A will only be opened when the arm B of the siphon is tilled-that is, the position of the balancingweight must be adjusted on the lever F according to the height and diameter of the arm B of the siphon. The siphon is thus charged'or started automatically at the proper moment.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent 1. The combination, with a tank, of asiphon with an automatic valve at its outer end, as and for the purpose described.

2. The combination, with a tank, of the valve A, the siphon G, the lever F, pivoted to the outer end of the siphon, and the adjustable,

weight H, as and for the purpose specified.
